More Informations About Key Systems Make Clean Diesel Possible

There are more than 7 million diesel cars, SUVs, trucks and vans on American roads. Whether you’re in the market for a clean diesel vehicle or you’re simply interested in learning more, it helps to have a basic grasp of three key technologies used to reduce diesel emissions and help new-gen vehicles earn the clean diesel moniker.

Exhaust Gas Recirculation (EGR)
Efficient diesel combustion requires large volumes of air and extreme heat. Unfortunately, these two factors also encourage the formation of nitrogen oxides (NOx), a family of pollutants the EPA now strictly regulates. NOx contaminants contribute to smog, acid rain and ailments such as asthma, bronchitis and emphysema.

To reduce NOx emissions, some clean diesel engines incorporate EGR systems that recirculate into the engine gases from the exhaust. Introducing these gases reduces overall air volume and cools engine temperatures to discourage NOx formation. While this method can be quite effective, its effectiveness can vary based on driving and load conditions, and it can increase by as much as 30% the production of particulates, hydrocarbons and carbon monoxide (CO).

Selective Catalytic Reduction (SCR)
Selective catalytic reduction represents an alternate approach to NOx reduction. As the exhaust stream travels through the SCR system, it passes through a catalytic chamber and is sprayed with a urea-based diesel exhaust fluid (DEF). The ammonia in the fluid reacts with NOx prompting a chemical reaction that converts the harmful pollutant into its base components, nitrogen and water, which can safely be released.

SCR is an effective way to decrease a range of emissions. It reduces NOx by 90%, hydrocarbons and carbon monoxide by 50% to 90%, and particulates by 30% to 50%. The process itself is automatic and requires no driver intervention, but to ensure a continuous supply of diesel exhaust fluid, vehicles are designed with an onboard tank to hold the fluid which must be replenished on a regular basis. To prevent drivers from circumventing the SCR system, some are designed to lock the starting system the next time the car is started if the DEF levels have fallen below an established level.

Diesel Particulate Filter (DPF)
To further reduce emissions, vehicle makers also install a diesel particulate filter in the exhaust pipe to trap soot and particles before the exhaust is released. While many DPFs are classified as self-regenerating, a dirty one can cause engine issues, so the filter should be removed and cleaned every 80,000 to 120,000 miles.

Many clean diesel vehicles rely on some combination of these technologies. Most incorporate EGR or SCR systems, supplemented with diesel particulate filters to further reduce emissions by straining any remaining soot and particles from the exhaust stream.

Some Benefits of Window Tinting

You may have considered getting your car’s windows tinted because you like the increased privacy, or because you want to protect your upholstery from fading. But did you know that window tint can also benefit your health? Here are some ways having good-quality window tint installed can keep you healthy.

Protects Against Skin Cancer
The sun streaming through your car window is made up of ultraviolet rays that can damage skin over time. This can lead to prematurely aged skin, or far worse—skin cancer. Studies have shown that people who drive a lot are more prone to skin cancer and other skin problems on the driver’s side of their body. Dr. Albert Kligman, a professor of dermatology at the University of Pennsylvania Medical School, said this: “Long-time drivers are found to have rougher, more pigmented skin with greater solar damage on their driver’s side.”

The good news is that the film used to tint car windows can reduce these harmful UV rays by up to 99%. This is an important precaution to take, especially if you spend a lot of time on the road.

Other Health Benefits
In addition to protecting your skin, window tint can help keep you comfortable and healthy in other ways, too. Tint can reduce the heat inside your car by as much as 60%. This helps prevent overheating and heatstroke without needing to run your air conditioner as much, which saves gas—and is therefore good for both the environment and your wallet.

The shading that window tint provides is also good for your eye health. You’ll have improved vision and ability to see all around you. This means less eyestrain and eye fatigue when you’re driving in bright sunlight.

Safety
Besides the benefits above, window tinting can also help you stay safe in the event of a collision. The tint film is attached to the window with adhesive, and this serves as a bonding agent for the window glass if something causes it to break. The small shards of glass will have more chance of staying together, reducing injury to the driver and passengers. In some cases, the tint film may even provide a barrier that’s enough to keep a person from going through the window.

Tips To Protect Your Car from Sun Damage

Did you know your car’s interior can reach a temperature as high as 140 degrees Fahrenheit on a hot, sunny day? It’s probably no surprise that this amount of heat and the sun’s ultraviolet rays can do a number on your upholstery, dashboard, and other components. Taking steps to protect your vehicle before the damage is done is the smart way to keep the inside of your car looking like new.

Quick Fixes
The cheapest and simplest way to protect your car while you’re not driving it is to set up a sunshade in your windshield when the car is parked. These screens reflect the sun’s rays, which means you’ll come back to a cooler car with an interior that hasn’t been baking while you’ve been gone.

Since a reflective screen isn’t any use while you’re driving, you’ll have to turn to other methods. Seat protectors are a good way to prevent bleaching, fading, and cracking of leather or cloth upholstery. If your seats are leather, use a good-quality leather conditioner frequently—this will also help protect against creasing and cracking.

Another easy way to minimize damage from the sun is to ensure that the surfaces in your car stay clean. Dust, dirt, and other particles can cause scratches, or they can even get baked by the sun into a film that’s extremely difficult to remove. A few minutes with a duster or clean cloth will make a big difference in the long run.

Window Tinting
One of the best things you can do to protect your interior is have your car’s windows tinted. The film that’s applied to the windows can block as much as 99% of harmful UV rays. This isn’t just good for your health, it’s good for the interior of your car, too. You’ll also get additional benefits like reduced glare and less fuel consumption (since your car will be cooler and you won’t have to run the air conditioner as much).

When you take your car in to have the windows tinted, you’ll be able to choose from several different types of tint film. Some are very dark, while others (like the newer crystalline film) are only slightly tinted, so you won’t even be able to tell the film is there while it’s protecting your interior.

Window tinting is especially helpful in regions that get a lot of heat and sunny days, but even people who live in fairly gloomy climates can benefit. Make sure to check the state regulations that apply to window tinting in your area to make sure you’re staying on the right side of the law.
